Connect your electronics properly. This collection covers the marine cables that link instruments, plotters and sensors into a working system: NMEA 2000 backbone and drop cables, connectors and terminators, NMEA 0183 cabling, power cables, transducer extension cables and display interconnects, complementing our dedicated Raymarine, Garmin and Simrad cable ranges.
Marine data networks are only as reliable as their cabling - genuine marine cables use tinned conductors and waterproof connectors that survive damp lockers and mast runs where ordinary cable fails. When planning an NMEA 2000 network, sketch the backbone first, count your drops, and remember both terminators and a dedicated power feed. If you're not sure which cable your instruments need, tell us the make and model of the devices at each end and we'll identify it.
Frequently asked questions
What is the difference between NMEA 0183 and NMEA 2000?
NMEA 0183 is an older point-to-point wiring standard connecting one talker to listeners, while NMEA 2000 is a modern plug-and-play network where all devices share a single powered backbone - most current instruments use NMEA 2000.
Can I extend a transducer cable?
Yes, using the manufacturer's dedicated extension cable for that transducer - avoid cutting and splicing transducer cables, as it degrades the signal and can void warranties.
What do I need to build an NMEA 2000 network?
A powered backbone cable with a terminator at each end, a tee and drop cable for every device, and a 12V power feed - then each instrument simply plugs into the nearest tee.
